1 - Background 

ABOUT THE APPROVALS PROCESS 

Regulations 25-27 of the Water Supply (Water Quality) (Scotland) Regulations 1990 provide 

for the approval of substances, products and processes used in the provision of public water 

supplies. From 1 st January 2004, regulations 27 - 29 of the Water Supply (Water Quality) 

(Scotland) Regulations 2001 replace the 1990 Regulations. 

The <strong>Committee</strong> on Products and Processes 

The <strong>Committee</strong> on Products and Processes for Use in Public Water Supply (the <strong>Committee</strong>) 

advises the Scottish Executive Drinking Water Quality Division on approval issues. The 

<strong>Committee</strong> is an advisory non-departmental public body. It consists of six members with 

expertise in engineering, materials science, toxicology, chemical analysis, water treatment 

and consumer relations. Details of the current membership are given in section 3. 

The <strong>Committee</strong> meets every two months and the dates of the <strong>Committee</strong> meetings are posted 

on the DWI website: http://www.dwi.gov.uk/cpp/index.htm 

The Drinking Water Inspectorate provides technical and administrative support to the 

<strong>Committee</strong>. The <strong>Committee</strong>’s Technical Secretariat can be contacted on 

cpp@defra.gsi.gov.uk 

The Annual List of Approved Products 

A list is published each year of all substances, products and processes for which approval has 

been granted, refused, revoked or modified, or for which use has been prohibited. This 

document is posted on the Scottish Executive website. 

2 - Report for 2003 

Impact of the 2000 and 2001 Regulations 

From 1 st January 2004 regulations 25 - 27 of the 1990 Regulations are replaced by regulations 

27 – 29 of the 2001 Regulations. The principal changes in the new Regulations are: 

• Precedence is given to European standards and European Technical Approvals 

• No provision for unapproved use at the water undertaker’s discretion 

• No provision for traditional use exemptions from approval 

• Introduction for the purposes of testing and research must be authorised by the 

Government Authorities 

Regulation 25 letter 5/2003 provides specific guidance on the new requirements for small 

surface area products that were formerly eligible for unapproved use. 

Approvals 2003 1 Printed December 2003

<strong>Committee</strong> Business 

During 2003 the <strong>Committee</strong> met on six occasions: 

• 101 applications for approval were considered, including 45 new applications 

• 51 products were approved and no product was refused approval 

• 19 products were revoked as a result of an audit and 9 products as a result of the 

prohibition of the use of PVC pipes with lead stabilisers 

• The Authorities gave approval to the modification of conditions to 1 currently listed 

product 

• The Authorities modified the national conditions of use for 1 water treatment 

chemical 

Communications with water industry and approval holders 

Five Regulation 25 letters were issued in 2003: 

• 1/2003 announced the issue of the 2002 list of approved products. 

• 2/2003 advised of the changes to national condition of use for polyacrylamide 

flocculants 

• 3/2003 reminded water companies and suppliers of PVC-U water supply pipes about 

the prohibition of the use of lead-based compounds in the production of PVC-U water 

supply pipes that takes effect from 25 th December 2003. 

• 4/2003 advised water companies on requirements for the civil engineering uses of 

concrete in water treatment works. 

• 5/2003 gave guidance on the requirements under Regulation 27 of the 2001 

Regulations for approval of small surface area products. 

Audit of approved products 

A requirement for audit of approved products was introduced in July 2002 and the 

programme of auditing, which started in Autumn 2002, has continued throughout 2003. To 

date 144 products have been audited and 35 formerly approved products have been removed 

from the 2003 List of Approved products. Some products have been removed from the list 

because they are no longer available; in other cases approval has been revoked because the 

product failed the audit tests or because the approval holder had failed to comply with a 

condition of approval. Full details of products removed from the 2003 List are contained in 

Appendix 2 and 3. 


European developments in construction products and treatment chemicals 

The majority of chemicals and filter materials for drinking water treatment are now the 

subject of European standards. A full listing of standards published by BSI in its BS:EN 

series is contained in Appendices 1.6 and 1.7. Appendix 1.8 lists the European standards for 

testing the effects of organic products and materials on water intended for human 

consumption. During 2003 the UK made a notification under Directive 98/34/EC on the 

notification of new technical requirements. Details are given above in Communications with 

water industry and approval holders. 

DWI provides the UK’s regulatory representation on the European Commission’s Regulatory 

Group - Construction Products Drinking Water. This Group is developing the European 

Acceptance Scheme for drinking water construction products. The EAS will provide 

harmonised arrangements throughout the European Union for testing and acceptance of 

drinking water construction products. Progress with the EAS and a copy of the interim report 

are posted on the DG Enterprise website: 

http://europa.eu.int/comm/enterprise/library/enterpriseeurope/issue10/articles/en/enterprise12_en.htm 

The EAS will eventually replace the UK’s national approval requirements. DWI has a number 

of initiatives underway preparing for transition from national to European requirements for 

testing and certification. These include: 

• Meetings to disseminate information about the EAS and its implications for the UK 

(details of current activities are on the DWI website: 

www.dwi.gov.uk/cpp/seminar.shtm ) 

• Certification and testing infrastructure. BuildCert and BSI are now notified bodies 

for the purposes of the EAS. The <strong>Committee</strong>’s designated test laboratories are being 

encouraged to provide testing services 

• Research to assess the impact of European test requirements for the UK water 

industry and its suppliers 

• Where appropriate, early implementation of European test requirements 

The EAS will replace the testing and certification responsibilities of the Water Regulations 

Advisory Scheme and the approval powers of the Government Authorities. In preparation for 

the EAS, WRAS and the <strong>Committee</strong> now use jointly designated test laboratories. 

CPP Website 

This has been subject to major revision during the year to take into account: 

a. New layout/presentation 

b. Introduction of the new Regulations at the end of 2003. 

c. Revision and publication of relevant European Standards as BS EN numbered standards 

d. Progress within Europe of the development of the proposed European Acceptance Scheme 

(EAS) for construction products used with water intended for human consumption 

e. The first of a series of Frequently Asked Question (FAQ) information sheets 

f. New application forms and revised test methods 

g. Replacement of the guidance to applicant with new advice sheets, “instructions for use” 

guidance and test protocols 

h. Advance posting of <strong>Committee</strong> meeting agendas.

LIST OF SUBSTANCES AND PRODUCTS APPROVED UNDER 

REGULATION 25 

Products approved by the Government Authorities for use in public water supplies 

are listed in three Parts. Part I includes products based on chemicals that are not 

subject of a BS EN. Part II lists construction products and Part III lists membranes 

and filters. All the products must be used in accordance with the relevant conditions 

of approval, including the three general conditions of approval reproduced below: 

(1) That use is in accordance with an Instructions for Use document. Approval 

holders must provide Scottish Water with copies of the Instructions for Use 

Document that was considered by the <strong>Committee</strong> when approval was 

recommended. 

(2) That the approval of the Government Authorities is obtained in respect of the 

following: any change in the formulation of the approved product, including 

change in source or identity of raw materials; any change in the manufacturing 

process, including location of manufacture; any change in designation of the 

approved product; and any change in name or ownership of the organisation 

holding the approval. 

(3) That the producer shall ensure that the product is tested for conformity with its 

formulation, and the source or identity of its raw materials, at such intervals and 

by such persons as may be determined by Scottish Ministers. The results of such 

testing shall be sent to the Authorities. 


PART I CHEMICALS 

As a consequence of the publication of European standards (BS: EN) for drinking 

water treatment chemicals, products that conform to a BS: EN may be used without 

the approval of Government Authorities, providing that national conditions of use are 

observed – see Appendix 1.6. These products are therefore no longer listed in this 

publication. 

Note: BS:EN standards for drinking water treatment chemicals do not contain 

mandatory requirements for attestation of conformity. Scottish Water are 

expected to stipulate appropriate attestation requirements in their procurement 

contracts. A full list of chemicals which are subject to a BS EN is given in 

appendix 1.6 

The following products either are not covered by a BS EN standard, or do not 

conform fully with the scope and/or requirements of a published BS EN. For all of 

the chemicals listed the following general national condition of use applies: 

The method of use and the purity of these products shall be such that, in the case of 

water for public supply, the water so treated meets the requirements of the Water 

Supply (Water Quality) (Scotland) Regulations 2001.

Subterra 

Fast-Line 

(i)All water undertakers and contractors must apply the lining in accordance with the 

operational requirements set out in “In-situ Epoxy Resin Lining – Operational 

Requirements and Code of Practice 3rd edition”, published by WRc. 

(ii)The resin must be manufactured and applied under the effective control of a BS EN 

ISO 9000 Quality System and approved by a third party certification organisation. 

(iii) Lining equipment must be fitted with a flow and pressure monitoring system, or 

system with equivalent performance, which provides a continuous numerical visual 

display and a minimum of 2 copies of a printout showing a record of the resin and 

hardener delivered to the spray head. The equipment must dispense the resin and 

hardener within ±5% of the correct mix ratio. The system must also give appropriate 

audible-alarm and abort responses if the mix-ratio is out of specification. 

(iv) From completion of material application, the lining shall be air cured for a 

minimum period of 16 hours before uncapping and subsequent inspection, 

disinfection and return to service procedures can commence. 

(v) Scottish Water’s appointed representative must obtain or must be 

provided with copies of the records listed below before each section of the main is 

accepted for return to supply: 

a) a record of weight measurements of resin and hardener made to check the mix 

ratio prior to each operation; 

b) the temperatures of the resin and hardener in the storage tanks; 

c) a continuous hard-copy record, which indicates the proportions and quantities of 

resin and hardener delivered to the spray head, and a record of the length and 

diameter of main renovated; 

d) a record of the pre-cure inspection, including the assessment of the quality, 

uniformity and thickness of the lining; 

e) a record of the post-cure inspection including the assessment of the quality, 

uniformity and hardness of the cured lining; and 

f) a closed-circuit television recording of all sections of renovated main and the 

results of the inspection of any pipe samples taken. 

Condition (ii) above should be deemed to be satisfied, notwithstanding the fact that 

the contractor who applies the resin has not achieved full certification of their Quality 

System, so long as the contractor has been accredited by an Approved Certifying 

Body and not more than 18 months have elapsed since the date of the accreditation. 

Where WRc approved the contractor before 7 July 1992, he shall be treated for this 

purpose as if he had been approved on that date. Scottish Water and approval holders 

should encourage contractors to register with a certification body which has been 

accredited by the National Accreditation Council for Certification Bodies for the in- 

situ applied epoxy resin lining process. Contractors which have satisfied the 

requirements of condition (i) above are listed in Appendix 4. 


For products in section 

3.C.1- 3.C.2 based on

following 

conditions apply unless 

otherwise indicated: 

(i) the minimum cure time 

is not less than 16 hours; 

and 

(ii) the minimum cure 

temperature is not less

Conditions if product is used as a cleaning agent: 

(i) the dose must be such that the final concentration in 

the water used to wash installations does not exceed 

1000 mg l -1 of free available chlorine; 

(ii) that following cleaning and disinfection, the 

installation is flushed to ensure that the residual chlorine 

concentration is acceptable to consumers; and 

(iii) permission or consent for disposal of any 

wastewater generated to a sewer or watercourse must be 

obtained from Scottish Water or the 

Scottish Environment Protection Agency, as appropriate. 

Scottish Water should check with their suppliers to 

ensure that products to be cleaned and disinfected will 

not be adversely affected by the concentration of 

chlorine to be employed. 

Conditions if product is used as an emergency 

disinfectant: 

(i) where circumstances are such that the water being 

treated is not grossly contaminated, and a controlled 

contact time of not less than 15 minutes between dosing 

and taking it into use can be maintained, not more than 

10 mg l -1 of sodium dichloro-isocyanurate compound 

should be applied and not more than 1mg l -1 of free 

residual chlorine should be present at the end of the 

relevant contact time. It is recommended that consumers 

should be exposed to such waters containing chloroisocyanurates 

for only as long as is required to restore 

conventional treatment, or for no more than 90 days in 

any period of a year, whichever is applicable; 

(ii) under circumstances where water sources may be 

grossly contaminated, to ensure inactivation of most 

likely harmful organisms, up to 20 mg l -1 sodium 

dichloro-isocyanurate may be added, with a 


1198:1998 Sodium dihydrogen 


12121:1999 Sodium disulfite 

12173:1999 Sodium fluoride 

recommended contact time of 15 minutes before use. It is 

recommended that consumption of water dosed at this 

rate of treatment should be for only as long as is 

necessary before it is possible to effect control of the 

residual chlorine after contact to 1 mg l -1 , and then to 

follow the requirements set out in condition (i); and 

(iii) should it be necessary for specific groups of 

consumers to be exposed to water containing chloroisocyanurates 

for periods greater than 90 days either 

continuously or in a year, it is recommended that
